[June 18, 2014]LOS ANGELES (Reuters) - A U.S. Air
Force installation in Los Angeles was placed under a security lockdown
for more than six hours on Tuesday afternoon as police investigated a
report of a suspicious person at the base.

The Los Angeles Air Force Base, which serves as an administrative
support post for a U.S. space and missile center in Colorado but
conducts no flight operations of its own, was locked down as a
precaution after security personnel received a report of suspicious
activity on the base, the installation said.

The nature of the activity that prompted the alert was not
specified, but the lockdown was lifted and the base was reopened at
about 8 p.m. local time, once a building-to-building search found no
sign of an actual threat, a base statement said.

The nearby Hawthorne Police Department said in a Twitter message
posted at the start of the lockdown that it was assisting in the
investigation of a "possible suspicious person on base," located
about a mile from Los Angeles International Airport.

Local television station KTLA-TV reported a person was seen wearing
a vest or backpack with wires protruding from it and possibly
carrying ammunition magazines. There were no reports of shots having
been fired.

Several streets surrounding the base were shut down during the
investigation.

According to its website, the Los Angeles Air Force Base provides
administrative and base services to the personnel assigned to the
Space and Missile Systems Center at Peterson Air Force Base in
Colorado.
